mechanical error, operator error or possibly something else? maybe something with the tracks. now, the train's conductor who was injured, himself, in this derailment has said that there was an issue, possibly with the braking system. but these recorders are really significant because they can tell investigators down to the second what was going on with the air pressure in the braking system. so they will be able to tell to the one-second intervals whether there was an issue, whether the brakes did malfunction and, also, possibly, tony, whether this train was going too fast. there were a enough witnesses, a number of people on board who said that the train was just going too fast, well above the 30 miles per hour that it's supposed to go. so we could learn that here in a few minutes. >> jonathan, if you would, take a moment and describe that scene. what is it like there, and have the officials started to upright all of the cars that de-railed? >> really, tony, they are at the final stages, i would say, at least here.
